I am really curious about the Genalex rectifier tube. I really like the 12AX7's of theirs. Retired all my old 12AX7. Very happy that this might be the tube era?
5AR4/GZ34 Rectifier Tubes
Is anyone currently making a tube of this type that rivals the performance of the best NOS Mullard tubes? I'm surprised that Sophia, Psvane and others appear not to have offered this tube. Suggestions?
